Don’t get me wrong I really like the idea of having the full control of how our profile looks like. However, now that people can easily hide their game history data from their profile, and also you can hide your match history from websites like dotabuff, there is literally no way for me to understand if someone is smurfing in my game. So there is really no functionality of the “Smurfing” button in the report page.
